ok, so the sex thing.. me too.. totally not into it at all this pregnancy!
the birth thing - trust me, you will be fine! I had fears of the epidural but was totally fine when they gave me one (even though it didn't work for me! stupid!!!!) you are in so much pain you just don't care!
with the delivery - again, you just want it out so you don't care!
The worst part for me (and I'm scared now because i know what its like!!) is the feeling for dilation! its sooooo uncomfortable! I would rather deliver than have to have that again!! eeeekkkk!!!!
